To all 'Loh/om it may concern:

Be it known that we, LEWIS W. JOHNSON and HILBERT J. FALK, of New Orleans, in the parish of Orleans and State of Louisiana, haveV invented certain new and useful Improvements in Apparatus for Producing and Burning Hydrocarbon Vapor, of which the following is a description sufficiently full, clear, andy exact to enable those skilled in the art to which it appertains or with which it is most nearly connected to make and use the same.

The present invention relates to the production and burning of hydrocarbon vapors, and the chief aim is to increase the ratio of efficiency in heating or lighting to the consumption of fuel over whatA has heretofore been attained. We propose to accomplish this by a novel arrangnient of means for treatresting upon a suitable base b, which also supports a similar tank'c, the latter receiving its supply of fluid from the first-mentioned tank through a valved pipe d, connecting the two tanks near the bottoms of the same. The tank a is charged with i its supply of liquid hydrocarbon through an opening atl the top, in which'there is a screw-plug? v e, and the said tank receives a Vcharge of compressed air through a suitable valved pipe connection f, entering the upper portionv of the tank and equipped with appropriate coupling means whereby it may be connected with a source of compressed air.

A pipe g extends downthrough the top of the tank a to near the bottom of the same, where it is fitted with a wire-gauze cap g', constituting a strainer, through which the oil is forced under pressure of the air in the upper part of the tank. A pipe h extends out of the top of the tank a and joins the pipe g a short distance beyond the point where the latter emerges from the tank, this pipe h having a check-Valve h incorporated in it and being designed to convey compressed air from within the reservoir to the oil conduit or pipe g for ad mixture with the oil passing through' the latter. v be entrained by the oil as the latter passes under pressure through the pipe g.

A pipe t' extends out of the upper portion of the tank a across to the tank c and into the same and is connected by an elbow t" with a It will be seen that such air will pipe i2, which depends to within a short distance of the bottom of the tankc, where it is equipped with a flaring nozzle sof wire-gauze. The level of the oil within the tank c is kept some distance vabove the said aring nozzle, and compressed air issuing through the latter forces its way through the oil and is carbureted and collects in the upper portion of the tank. The supply of compressed air forcarbureting purposes is regulated by means of a valve i4 in thepipe t'. Some of the carburete'd air is entrained' by the oil passing up the pipe g, the latter being connected by a T-couplingj and a pipe 7" with the interior of the tank c, said pipe j having a valve i2 for controlling the lpassage of carbureted air to the pipe g and also being provided with'a check-valve l7'3 to prevent oil owing through the pipe into the tank c. A pipe 7.9 leads out of thetop of the latter, it being provided withv a valve 7a', and this pipe conducts carbureted air to a burner, hereinafter described, for completing vaporization of the oil which issues from the tank a through the pipe g.

We prefer to use a mixture of gasolene, spirits of camphor, and wood-alcohol in the tanks in the proportion of ten per cent. of spirits of camphor and ten per cent. of woodalcohol to eighty per cent. of gasolene-oil, this mixture having proved to give the best results in candle-power of lights burning vapor as produced by the operation of our invention.

lVe have here shown a burner for illuminating purposes; but of course it is to be understood that our invention maybe employed in apparatus for heating as well as illumiloroY nating. The above-mentioned burner comprises a drum-like head fm with `a perforated cap 'm' and a tubular appendage m2, `Within which there is a sin uous passage-way m3, having a flaring mouth m4 at its lower end for receiving the Vapor, the force with which the latter enters being broken by passing through the sinuous passage-way, whereby injury to the mantle is guarded against. A bell m5 spreads the vapor as it approaches the burnercap m'. A pipe n encircles the burner-head min one or more coils and on one side thereof extends to a valve-casing n', with which the pipe g communicates, the said casinghaving a needle-valve n2 for controlling the flow of oil. On the other side of the burner-head the pipe n extends down below the tubular appendage of the head and thence laterally to a valve-casing o, located directly below the flaring mouth nof the vapor passage-way m3 and containing a needle-valve o for controlling the passage of vapor to the burner. Such vapor passing across from the valve-casing o to the tubular appendage of the burner entrains air, and the snpplyof air for this purpose is regulated by means of a sliding sleeve p, fitting the said tubular appendage and havinga pendent adjusting-rod p. A burner q is located just below the bend n3 of the pipe n, said burner being mounted on the end of a pipe q', whichenters a valve-casing q2, having connected with it the carbureted-air conduit 7c and being equipped with a suitable valve g3. The burner q is ot' cylindrical form, with a perforated cap q, and is preferably formed in one side with an opening for the admission of air, which opening is controlled by a damper in the form ot' a sleeve g5, rotatable about the burner by means of a handle q. An incandescent mantle r is suspended from a suitable support r', so as to surmount the burner-head fm, and just below the latter there is a globe-support s.

It will be seen that with the construction of apparatus described compressed air within the tank a, acting upon the body of liquid hydrocarbon therein, forces the same up the pipe g, and when the valve t7"'2 is open carbureted air will be entrained in the pipe g, and air under pressure will also enter the same through the pipe h, so that the valve t controls the passage through the pipe g of a mixture of oil, carbureted air, and air under pressure. Such mixture passing under control of the Valve 'n2 into the pipe n will be vaporized at first by the heating ot' the pipe 'n through the operation of the carburetedair burner q, and the vapor thus produced passes across under control of the valve 0 into the sinuons passage-way m3 and thence to the main burner. When the latter is in operation, vaporization of the liquid iiowing through the pipe n Will take place by reason of the heating of said pipe in the portions thereof surrounding the burner. Ne may,

however, and generally do keep the burner q in operation to insure complete vaporization ot the oil before it passes to the main burner, said burner q being kept supplied with carbureted air from the tank c.

It will now be seen that an apparatus such as here shown and described is well calculated to accomplish the objects primarily stated. However, it is to be understood that the invention here disclosed is capable of being embodied in other forms than that in which we have preferred to show it in the present case.
